Add the device tree for the QCS615-based Talos EVK platform. The
platform is composed of a System-on-Module following the SMARC
standard, and a Carrier Board.
The Carrier Board supports several display configurations, HDMI and
LVDS. Both configurations use the same base hardware, with the display
selection controlled by a DIP switch.
Use a DTBO file, talos-evk-lvds-auo,g133han01.dtso, which defines an
overlay that disables HDMI and adds LVDS. The DTs file talos-evk
can describe the HDMI display configurations.
The initial device tree includes support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort interface
- SN65DSI84ZXHR DSI-to-LVDS bridge
- Wi-Fi/BT

can here be dr_mode = "peripheral";
when sw1 = off
usb port 0 can be device port to usb adb.
usb port 3 be host mode.

In our hardware design, the USB0 controller is a USB 3.0-capable
controller whose high‑speed (HS) differential lines are routed through
a mechanical switch.
a) During EDL (flashing) mode:
The HS lines are explicitly routed to the Micro‑USB port.
This allows the SoC to enter "device mode" for firmware flashing.
b) After EDL completes (normal operation):
The mechanical switch is driven to route the HS signals to the on‑
board USB 3.0 hub.
The hub connects to four Type-A ports, all designed for host mode
only.
The Micro-USB connector is now electrically disconnected.
Why host-only mode: Once the switch routes to the hub, there's no
electrical path back to the Micro-USB port. The USB controller can
only talk to the hub and its downstream Type-A ports, which are wired
for host mode only. Device mode is physically impossible in this
configuration.
Therefore, USB0 must be configured as host-only in the device tree,
since device mode cannot work after the system boots.
The USB1 controller supports USB 2.0 and has its data lines directly
routed to a Type-A connector. This hardware design restricts the
controller to host-only operation, preventing any peripheral/device
mode functionality.

Please add a comment regarding EDL-mode DIP switch and describe the
onboard HUB in the DT. Additionally consider adding the USB-peripheral
overlay, corresponding to the EDL-mode configuration as some labs will
not trigger the DIP switch at runtime and settle with the
peripheral-only setting for the USB controller.
